PIN HINGE.

Application filed. May 6, 1929. Serial No. 360,963.

This invention relates to the manufacture of pin ornaments and hasespecial reference to the hinge connection of the pins.

The invention resides in the reduction of cost-s in hingedly connectingpins with the bodies of ornaments.

In order that the invention may be fully understood, attention isdirected to the accompanying drawing forming a part of'the followingspecification, and in which Figure 1 is a side view of one form'of moldused in making a hinge connection in accordance with the invention.

Fig. 2 is an enlarged section taken on the line 22, of Fig. 1, showing apin in position on one of the mold parts preparatory to the pouring ofthe molten metal into the mold to form the body of an ornament and thehinged connection therewith of the pin.

Fig. 3 is a view similar to Fig. 2, but show ing the metal poured intothe mold.

Fig. 4 is a side view of an ornament constructed in accordance with theinvention. Fig. 5 is a back view of the ornament. Fig. 6 is an enlargedsection taken on the line 6-6, of Fig. 5.

. Referring now more particularly to the drawing, it will be apparentthat in accordance with the invention use is made of a suitable moldconsisting of companion parts 10 and 11 which form a cavity 12, thewalls of which conform to the shape of the ornamental body desired to beformed. The part 11 of the mold has abore or hole 13 which opens to arecess 14 in the inside face of said part 11 for the purpose ofaccommodating a pin 15 having an eye 16 on one end thereof. The

12. Some of the metal flows into the recess 14 to opposite sides of theeye 16 and through I the opening in the eye. When the molten metal hascooled, the body 17 of an ornament will have been formed with the pinconnected with the body 17 by a pivot or pintle 18 integral with thebody. The mold parts 10 and 11 may be readily separated enabling theremoval of the ornament body with its pivotally or hingedly connectedpin. The body 17 also has connected therewith a keeper 19 in the moldingoperation but does not form a part of this invention. The keeper 19serves with the pin 15, as shown in dotted lines in Fig. 4, for anobvious purpose.

I claim:

An ornament having the combination of a molded body, a pin having an eyeon one end thereof, and integral provision on said body which extendsthrough the eye of the pin hingedly connecting the pin with said body.

Signed at New York, in the county of New York and State of New York,this 3rd day of May, A. D. 1929. v

pin 15 is made of metal having a melting point higher than that of themetal used to produce the body of the ornament.

In practice the pin 15 is positioned in the bore or hole 13 with the eye16 thereof disposed in the recess 14, the latter beinglarger than theeye 16 to present spaces at the'opposite sides thereof. When the moldparts 10 and 11 are brought together the recess 14 will be incommunication with the cavity 12. The mold parts 10 and 11 are broughttogether with the pin 15 positioned as explained, after which moltenmetal is poured into the cavity ISRAEL W. COOPER. 75 I
